The gas gauge always reads full or 3/4 full. How can I fix this problem without taking it into a shop. Also, the center consol keeps beeping and giving me warnings like "check oil" or "service 4wd switch." I have had the oil changed twice and I am wondering if there is a switch that I can flip to reset it? I'm sure there will be more work involved in it than flipping a switch, but it doesn't hurt to ask.

Re: Broken gas gauge and faulty sensor.
It might not be the gauge itself. it could also be the sending unit in the tank. this however requires you to remove the tank which is not an easy job. if you have a oil light on but the level is good it could be a loose connection on the sensor or the sensor itself. it is located in the engine block and has only 1 wire with a rubber boot connection. as far as the service 4 wheel drive light it may be that there is a loose connection or that the solenoid that ingages/disingages is faulty. please rate this solution. good luck and thanks.

2005 PT cruiser, i replaced the cam sensor with a aft market sensor my fuel gauge started reading wrong, and it didn't fix my problem so i replaced the cam sensor with a factory sensor it fix my running problem but the fuel gauge still reads wrong, with a full tank of gas the gauge reads 3/4 tank,
Most of the time its is the sending unit in the fuel tank. The test for it is to use a variable resistor that is hooked up to the wiring at the fuel tank and watch the fuel gauge if the gauge works ok thats makes 100% sure its the sending unit. At 245 ohms the gauge should read full, 180 ohms for 3/4 full, 160 ohms for 1/2 tank, 100 ohms for 1/4 tank and 42 ohms for empty. The color of wires at the fuel tank is purple wire and black wire. You can also use fixed value resisters. If the fuel gauge the wires from the sending unit to computer then to gauge for bad connections, shorts, broken wire and bad grounds. If the wires test ok that only leaves insterrment cluster or computer which even most dealers can't test eather one but the insterment cluster would be a more common problem then the computer. But about 95% of the time it will be the fuel level sensor in the gas tank that causes the problem. Good luck.
It could be a faulty sending unit, which will require the removal of the fuel tank. Make sure all of your fuses are good before you do anything else, as all the gauges are electrical. It is possible you have a bad gauge, but 9 times out of 10, it's the sending unit.
yes the most likly cause is that the fuel level sensor is faulty i would put a gas can in the back and go for a drive the a shop and have them check it. but i think if the truck wont take any more fuel it will be a faulty fuel level sensor.
hello, the problem could be in the sending unit. this is a wired potentiometer and if you have a broken wire in the potentiometer, then that is what would happen.
you can verify this by grounding the sending unit wire to ground. you will have a full tank reading always. then use the car and see if it will still bounce and very erratic. if does not do that, then the sending unit is the problem. if it still do the erratic reading, then there are more problems.
